Final Flashcards
All internal senses
Visceral senses
Tactile sensations (touch, pressure, vibration), thermal sensations, pain sensations and proprioception
Somatic senses
On surface of the body, sensing things externally
Exteroceptors
Senses to limbs and joints
Proprioceptors
Pressure, touch, motion, sound
Mechanoreceptors
Heat, cold, infrared radiation
Thermoreceptors
Respond specifically to pain
Nociceptors
Respond to light
Photoreceptors
Senses chemicals
Chemoreceptors
Stops overstimulation
Adaptation
Acute, well localized, rapid response (needle prick, something sharp)
Fast pain
Pressure, slow to respond
Slow pain
Pain on surface
Superficial somatic pain
Pain receptors buried in muscles, tendons and joints
Deep somatic pain
Pain receptors of internal organs not muscles
Visceral pain
Pain that is sensed on surface of body from internal organ
Referred pain
Sensations at the limb that was amputated as though it was still there
Phantom limb pain
Flow: (5)
- Receptor

Characteristics of special senses
Located only in head and very complex
5 general senses

- Pain
- Proprioceptive
- Visceral
5 special senses
- Smell

- Equilibrium
Primary olfactory area is located where
Temporal lobe
Gustatory
Taste
5 taste sensations
- Sweet
- Sour
- Salty
- Bitter
- Umami
Nearly 10,000 located on tongue, soft palate, pharynx and larynx
Taste buds
Primary gustatory center is located in which lobe
In parietal lobe
Gustatory nerves are located in which nerves
CN 7,9,10
Levator palpebrae superioris is located in which nerve
CN 3
Where do tears drain
Lacrimal puncta
What controls the shape of the lens
Ciliary body
Palpebrae
Eye lids
Clear mucous membrane that covers the white of the eye
Conjunctiva
Lacrimal glands
Where Tears are generated
Drains glands into eyes
Lacrimal ducts
Drain surface of eye into nasal lacrimal duct
Nasolacrimal canals
Front of eye
Cornea
Colored portion of eye, dilates or constricts
Iris
Layers of the eyes are called
Tunics
Sclera is also known as
Fibrous tunic
Choroid is also know as
Vascular tunic
Retina is also known as
Nervous tunic
What is the order of the three tunics from deep to superficial
- Nervous tunic
- Vascular tunic
- Fibrous tunic
Heavy blood supply is in which tunic
Vascular tunic
Allows light to be absorbed rather than scattered
Melanin pigmented epithelium
Center of the retina
Macula lutea
Optic disc
Blind spot
Responds to low light, only black and white
Rods
Responds to intense bright light, only color
Comes
Absence of one or more types of cones
Color blindness
Transparent protein;deep into the pupil and iris (it attaches to ciliary muscle)
Lens
Posterior cavity is filled with
Vitreous humor
Anterior cavity is filled with
Aqueous humor
What is the function of the virtuous humor
Hold eye in place
What is the function of the aqueous humor
Keep continuous flow of light
What disease is caused by a failure of drainage
Glaucoma
What is glaucoma
Increased intraocular pressure (IOP)
Keeps the eye inflated, keeps eye nourished
Intraocular pressure
Retina begins to move and detach from choroid layer below
Detached retina
What is the function of the radial muscle
Constricts to pull pupil open
What is the function of the circular muscle
In bright light, the pupil will constrict
Bending of light rays as they pass through something
Refraction
An increase in the curvature of the lens for near vision
Accommodation
Inward movement of the eye so that both are directed at the object being viewed. (Becoming a little cross-eyed when viewing things close up)
Convergence
Myopia
Nearsightedness
Hyperopia
Farsightedness
Nyctalopia
Night blindness
Primary visual area is in which lobe
Occipital

Ceremonious glands
Tympanic membrane
Ear drum
State of balance relative to the force of gravity
Static equilibrium
Maintenance of balance during sudden movements
Dynamic equilibrium
Opaque defect in the cornea or lens
Cataract
Inflammation of conjunctiva
Conjunctivitis
Loss of vision in the center field because of damage to the retina
Macular degeneration
Inflammation of the ear drum
